SPECIFICATION forming part oi' Letters Patent No. 393,859, dated December 4, 1888.

Application led March 25, 1886. Serial No. 196,523. (No model.) Patented in Germany February 6, 1884, No. 29,821, and Maly 5,

. 1885, No. 34,429; in France April 15, 1885, No. 168,287., and in Belgium April 15, 1885, No. 68,531.

T0 all whom. t may concern:

Be it known that I, MAX SCHNEIDER, of Doos, near Nuremberg, in the Kingdom of Bavaria, and German Empire, have invented a new and useful Improvement in Dampers for Fire-Place Stoves, of which the following is a speciiication, reference being had therein to the accompanying drawings, (no patents being obtained by me anywhere for this invention save in the German Empire, No. 29,821, dated February 6, 1884, and No. 34,429, dated May 5, 1885; France, No. 168,287,7dated April 15, 1885; Belgium, No. 68,531, dated April 15, 1885.) y

My invention relates to magazine-stoves; andit consists in certain improvements in the construction of the same, the tire-chamber being provided with suitable passages for the admission and circulation of air and devices for regulating' the same, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a vertical central section of my I improved stove. Fig. :2 illustrates a hinged plate or valve for the admission or exclusion of air and the rod by which it is operated. Figs. l3, 4, 5, and 6 are sectional views of details, showing modiiications in construction. Figs. 7, 8, and 9 show different constructions of airpassages of the stove.

In the base of the stove is an air-chamber, a, which surrounds the ash-hopper b, and in which the air circulates below the lire-chamber. The ash-box c is placed centrally in the base, as shown. The grate d is placed in position somewhat elevated, so that considerable air-space isleft between the grate and the hopper b. Across this space extends a rod, o', which rests in bearings on the uprights g, and is connected with a flap-valve, i', formed of a hinged plate, and a valve, f', formed of a plate or disk carried by the rod, the valve t" being to the rear and valve f being at the front of the stove. Both of said valves, being placed at opposite openings, may be operated simultaneously by means of the rod r, so that one of the valves is closed when the other is opened. The extended end of rod fr is fprovided with a handle, f, and a portion of the rod s is screw-threaded and provided with a threaded bearing, s0 that by rotating the rod it Inay be moved rearward, so that the disk f', being fixed to the rod, closes the adjacent opening', and the valve t" or the rod 'may be moved forward, opening the valve f", and valve i', being weighted at i?, is closed at the same time. The opening li, at which the valvel the arrow II indicates the counter air-current when valve z" is open, the valve f being closed. i

In Figs. 3, 4, 5, and 6 Inodications are shown in the construction of the valve-rod and its connections. In Fig. 3 the rod 7j, carrying disk-valve f at one end, is' provided with a crank form, c, at its opposite end, which has a support, k. d is a slide-valve by which the counter-current of air is regulated. A-pin, l', projects from .valve d and fits in an arm of the crank c', and when valve f is closed by turning the handle f the slidevalve d is opened by the movement of the crank. Another pin, e', Fig. 3, attached to valve d', is pressed in the smoke-box fm by a spring, g', and when valve f is opened, drawing the rod fr from valve d', the latter will be closed by the pressure of the spring g.

In Figs. 4 and 5 a further-modification is shown. The crank c is in construction simillar to that shown in Fig. 3; but a nap-valve, n', is used instead of the disk-valve f', the

valve n being opened or closed by means of the handle o', fastened to the slide-valve d. Vith this construction the effect above describedl is produced by means of the handle o in opening or closing valve Cl.

In Fig. 6 a slide, p, is used instead of disk f', and is connected with slide d by a lever, g. This lever is pivoted on a tripod, r', in the center of the ash-hopper. The handle s of the lever extends from the door t, as shown, and the slides p and d are respectively opened or closed according to the movement given lever g by means of the handle s.

lFor the purpose of dispensing with the disk IOO In Fig. Sl thebase of the stove isalso shown E divided bv the partition-wall S, and the back i or re wall, F, has an aperture, opening into the base-conduit and situated under the tire-box and e'rate l). An aperture, M is made in the front part ot' the heating` apparatus or in either sideof it. A rotary regulatine-ring, R, adapted to close or open these apertures severally, is applied, as shown. lYhen the front aperture, M, is open, the opposite aperture,O, is closed b v the ring". \\'hen the l'ront aperture, M, is open, the air entering' through it passes through the grate to the fuel and from thence to the chimne)Y in the direction of the arrow III. Then if, bv means of handle T, the regulating-ring' R is turned so that aperture M is closed and aperture() is opened,

' the counter-current of air passes under the grate toward the base in the direction of the arrow IV and the draft is at onee cheeked and combustion becomes slower.

I claim- 1. In a stove, a central chamber, an airpassage outside ot' said chamberandlcading toward the base ot' the stove, a valve opening;l from said chamber into said air-passage, and an opposite valve, both ot said valves being,` so connected that either valve maybe opened and the other simultaneously closed, substantially as and for the purposes` described.

2. In combination with a Stove having' a central chamber and a rear air-passage outside of Said chamber, a valve between said chamber and Said air-passage, an opposite valve, and a valve-rod connected with both valves and provided with a handle, the parts being so constructed that either valve ma)v be opened and the other valve closed by a movement ol' the handle, substantiall \v as set forth and described.

3. In a Stove, a valve-rod, f1', screw-threaded and provided with a handle and a threaded bearing', as shown, and opposite valves f and 1", connected with rod 1' and operated by said rod, substantialtvY as and t'or the purposes specified.

In witness whereof I have hereunto set my hand in presence ot' two witnesses.
